Freelancer Overview

Senior Consultant and Full-Stack Developer with over 21 years of IT experience across the energy, finance, and media sectors, specializing in complex system architecture, database design, and data processing. While my core expertise lies in full-stack development, my career has centered on building robust systems that ingest, clean, structure, and validate massive enterprise datasets. This deep technical foundation in data management and system design directly transfers to the rigorous data quality requirements needed for AI training and data labeling lifecycles. I excel at designing automated data pipelines, creating intuitive user interfaces for data input, and writing strict validation scripts to eliminate data errors. With a strong academic background in Engineering and Computer Science, I bring the disciplined structural analysis, taxonomy management, and backend engineering skills necessary to scale, organize, and secure high-quality datasets for modern AI initiatives.
